I'd like to add superscript on summation symbol, but I get an error message: Please, use mathaccent for accents in math mode. I can't use ^ symbol to add superscript.

Here is the code:

begin{equation}

    y & = beta_{0}+sumˆ{2}_{j=1}beta_{j}X_{j}+sumsum_{i<j}beta_{ij}X_{i}X{j}+sum_{j=1}beta_{jj}X_{j}textsuperscript{2}

    label{equation1}

end{equation}

  Welcome to TeX.SX! It's not at all clear where the superscript is meant to go. Besides, textsuperscript is not valid in math mode. And the & is out of place.

You have a wrong ^ character that is not a ascii character but possibly something with similar appearance and this is what causes the whole problem.

Your code with the correct character is something like:

documentclass{article}



begin{document}

begin{equation}

 y = beta_{0}+sum_{j=1}^{2} beta_{j}X_{j}+sumsum_{i<j}beta_{ij}X_{i}X{j}+sum_{j=1}^2beta_{jj}X_{j}^2

    label{equation1}

end{equation}

end{document}

And gives:

PS1: Not sure about the last power and the last upper limit of the sum, but you will see it works if you just delete your bad character and replace with the original keyboard's ^.

PS2: For readability never start a sum by its upper limit, but use first its lower limit instead.
